Avaya IP Office: 3641/3645 Randomly Powering Off

Affected Kit:

Avaya 3641 and 3645 (Spectralink/Polycom 8020 and 8030) wireless handsets

Problem Details:

Handsets appear to randomly power off, even when fully charged.

Cause:

Likely caused by loose or damaged connectors from the battery pack to the connectors inside the phone itself. Can be caused through general age of the handset, improper cleaning and of course, dropping the handset.

Solution:

Replacing the battery would be the first port of call, but if it is the phone connectors itself that are damaged, a replacement handset would need to be sourced.

ShoreTel: Adjust Handset Display/Power Settings On 400 Series Handsets

Introduction

This How-To covers adjusting the handset display/power settings on the ShoreTel 400 series handsets (420/480/480g/485g).

Steps:

1: Open Config File

Browse to the following location on your ShoreTel Director Server:

C:\inetpub\ftproot\phoneconfig

From here, there should be the following config files:

custom.txt (global changes to all 400 series handsets)
custom_IP420.txt (changes to all 420 handsets)
custom_IP480.txt (changes to all 480 handsets)
custom_IP480g.txt (changes to all 480g handsets)
customIP485g.txt (changes to all 485g handsets)
custom_MAC.txt (changes to specific handsets based on the MAC address of the handset)

Note: Depending on whether you want to make this a global change, a change to specific types of handsets or single users will depend on which file you want to change.

2: Choose The Parameters To Modify

You can modify the below display settings in this config file:

Idle Brightness – Intensity of the phone backlight when the phone is in the idle state (Default: 5. Other Values: between 1 and 100)

Idle Timeout – The number of minutes without phone activity before the phone transitions to the idles state (Default: 5. A value of 0 means the phone will never go into the idle state)

Sleep Timeout – The number of minutes without phone activity before the phone transitions to the sleep state (Default: 60. A value of 0 means the phone will never go into the sleep state)

Reduce Ethernet Power (Sleep Mode) – Determines whether or not the phone reduces Ethernet power when the phone is in a sleep state (Default: On. If Off is selected, Ethernet power is not reduced)

Suspend USB Devices (Sleep Mode) – Determines whether or not the phone supplies power to USB devices in the USB port of an IP485g when the phone is in a sleep state (Default: On. If Off is selected, USB devices are still powered when the phone is in a sleep state)

Sleep Inhibit Start Time – The time of day a phone display goes from the sleep state to an idle state. (Default: 06:00. Must be configured in a 24 hour clock format: HH:MM)

Sleep Inhibit Stop Time – The time of day a phone display transitions to the sleep state (Default: 19:00. Must be configured in a 24 hour clock format: HH:MM)

Sleep Inhibit Days – The days of the week when Sleep Inhibit Start/Stop are in effect (Default: Mon,Tue,Wed,Thu,Fri. Other Values: none, all)

Display Maximum Brightness – The maximum intensity of the phone backlight when the phone is not in an idle or sleep state (Default: 100. Other Values: between 1 and 100)

Please see the below parameters that need to be entered in the config file:

[power]
idleBrightness
idleTimeout
sleepTimeout
sleepEthernetLowPower
sleepUsbSuspend
sleepInhibitStartTime
sleepInhibitStopTime
sleepInhibitDays

[syscontrol]
displayBrightnessMax

3: Modify Config File

Add in the relevant parameters to the config file in the following format:

[group]
parameter=value

For example, if we wanted to change the idle brightness and the max brightness, you would enter the following:

[power]
idleBrightness=20

[syscontrol]
displayBrightnessMax=90

4: Save Config File

If you are creating this config file for a single extension, save the file as a new file and name it as follows:

custom_MAC.txt (where MAC is the MAC Address of the handset in question e.g. custom_00104928630b.txt)

Otherwise, just overwrite the existing config file as per the file names in step 1.

5: Reboot The Handset

Once the config file has been saved, reboot the handset and it should pull down the new config file.

Conclusion

After the phone has pulled down the new config file, check to see whether the changes have made a difference. If further adjustments are needed, modify the config file where necessary.
